Pedestrian protection device

Abstract

A pedestrian protection device includes a left airbag and a right airbag that are disposed in a vicinity of a rear end of a hood panel in a vehicle, and are arranged in parallel on vehicle width direction sides. The left airbag and the right airbag each include a cowl cover portion that is disposed following the vehicle width direction and covers an upper face side of a cowl. The cowl cover portions have end portion regions disposed coinciding with each other on up-down direction sides on end sides that are in proximity to each other. At least one of the end portion regions is configured in such a way that an internal pressure when inflation is completed is raised higher than that of a general region.

What is claimed is: 
     
       1. A pedestrian protection device, comprising
 a left airbag and a right airbag that are disposed in a vicinity of a rear end of a hood panel in a vehicle, and are arranged in parallel on vehicle width direction sides when inflation of each is completed, wherein 
 the left airbag includes a left cowl cover portion that is disposed approximately following the vehicle width direction and covers an upper face side of a cowl when inflation is completed, and 
 the right airbag includes a right cowl cover portion that is disposed approximately following the vehicle width direction and covers the upper face side of the cowl when inflation is completed, and wherein 
 the left cowl cover portion and the right cowl cover portion are configured to have end portion regions disposed coinciding with each other on up-down direction sides on end sides that are in proximity to each other when inflation is completed, and 
 at least one of the end portion regions is configured in such a way that an internal pressure when inflation is completed is raised higher than that of a general region of the left airbag or the right airbag. 
 
     
     
       2. The pedestrian protection device according to  claim 1 , wherein
 an upper side end portion region positioned on an upper side when inflation is completed is configured in such a way that an internal pressure when inflation is completed is raised higher than that of another general region. 
 
     
     
       3. The pedestrian protection device according to  claim 2 , wherein
 the left airbag and the right airbag are configured in such a way as to expand on a left and a right respectively of a wiper pivot disposed centrally in the vehicle width direction in a left and right pair of wipers, and 
 a lower side end portion region positioned on a lower side when inflation is completed is configured in such a way that an end edge is caused to neighbor the wiper pivot. 
 
     
     
       4. The pedestrian protection device according to  claim 3 , wherein
 the upper side end portion region is of a configuration disposed inclined in such a way that an end edge is lifted upward. 
 
     
     
       5. The pedestrian protection device according to  claim 2 , wherein
 a wall that separates the upper side end portion region and the general region is disposed in the left cowl cover portion or the right cowl cover portion.
